Auckland FC says a fan was involved in an assault that left a man hospitalised.
Police are considering charges against a 46-year-old man after the attack at Saturday's match against Western Sydney Wanderers.
Eight people were evicted from Mount Smart Stadium and two were arrested - and a visiting Wanderers fan needed facial surgery.
Auckland FC CEO Nick Becker says the accused man doesn't represent the club.
"We've got a great set of hardcore fans - known as the Port - who I think do everyone in Auckland proud. And it's certainly not one of them, it's not someone they would associate with and it's definitely no someone we want involved."
